Vehicle Performance in Adverse Conditions

Simulation-driven design using SIMULIA PowerFLOW and XFlow providing the environment for vehicle development in the real world

The vehicle development process must adapt with new engineering objectives. Performance challenges due to adverse conditions must be addressed earlier in the design process, and this requires a more coupled, collaborative approach, with earlier testing for robustness of the design to adverse conditions. 

This type of environment is impossible to obtain using physical tests due to the lack of test facilities as well as the unavailability of detailed prototypes for onroad testing. Since a fully detailed prototype is not available for road testing at this stage, and since wind tunnels are not equipped to model real-world conditions, simulation is the only option. Targeted design improvements addressing these failures have an adverse effect on other engineering objectives such as aerodynamic drag, vehicle styling, thermal protection or interior wind noise, and so these attributes should also be tested using simulation in the early design phase.

The engineering objectives related to adverse conditions are summarized below, organized by industry trends:

  1. Energy efficiency
  2. Increased technology
  3. Quieter vehicles
  4. Improved reliability
  5. Increased demand for SUVs and pickups
  6. Consumer perception of quality
